IMPROVEMENT IN STAVE-MACHINES.

Specification forming part of Letters Patent No. 46,068, dated January 31, 1865.

l' 0 all whom it may concern:

Beit known that I, IsAAo W. BowERs, of Ovid Centre, in the county of Clinton and State of Michigan, have invented a new and Improved Stare-Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side View ot' my invention; Fi g2, atransverse vertical section of the same, taken in the line .r fr, Fig. l.

Similar letters of reference indicate like parts.

This invention consists in combining two circular saws and two springs with a stavecutting machine.

The object of the invention is to saw the ends ofthe stares simultaneously with the cutting operation, so that they all will be of the same length, thereby avoiding the necesY sity of sawing the staves after they are out in order to render them of equal length.

A represents a framing in which a curved or segment plate, B,is fitted, and havinga knife, (l, attached to itslower end.

l) represents an oscillating bed, which is suspended in the framing A on journals a a, and has an arm, E, attached to it which is con nected with the moter thatdrives the machine.

F represents a series of ribs, which are attached to a curved or segment plate, G, in the framing A, below theknife or cutter O, the upper ends of said ribs projecting a little cutward beyond the knife or cutter C, as shown clearly in Fig. 2.

These parts are constructed and arranged similarly to many stave-cutting machines of that class which are provided with an oscillating bed. The bolt is placed on the bed D,

and the bed when forced upward pastthe knife or cutter has a stave cut from it by the latter.

H H represent two circular saws, the arbors J J of which are placed inbearingsJ. secured to upright bars b, the latter being attached to the framing at the rear of the knife or cutter O. The saws are driven by belts K K from a shaft L at the lower part of the framing.

M M are two springs of curved or bow form which are attached one end of them to the upper edge of the plate G and the other end to a cross-baro of the framing, said springs extending upward about to a level with the upper edges ofthe saws H H.

The saws H H rotate in the direction indicated by the arrows, and are placed a distance apart equal to the desired length of the staves to be cut, and as the staves are cut from the bolt the saws H eut the ends of the same, the staves being forced up between the springs and saws and two ribs onbearings, d d, at the outer side of the plate B.

The springs M M hold a stave after it is eut from the bolt until the succeeding one is being cut, the latter shoving the former upward and outward from between the springs and the bea-rings d d. A cut stave is thereby pre- Vented from falling back or down between the saws, being properly held ouiJ of the way of the cutter or knife and ascending bolt until the succeeding stave while being out forces it up and discharges it from the machine.

The bearings ofthe saw-arbors are designed to be adjustable horizontally and vertically to compensate for the diminishing diameter of the saws due to filing.

I claim as new and desire to secure by Letters Patent- The combination ofthe saws H H and springs M M, applied to a stave-cutting machine, to operate in the manner substantially as and for the purpose herein set forth.
